Pornhub took its first real hit in late March, when a Los Angeles federal court allowed a subpoena from Wankz.com that requires Pornhub to provide the “names, email addresses, IP addresses, user history, posting history, physical addresses, telephone numbers, and any other identifying … information” of users who uploaded several of Wankz.com’s porn videos to the porn giant. There are some 2,000 clips that Wankz.com says were uploaded without permission. Pornhub has until May 1 to provide the information, unless it challenges the subpoena. So far, the marketing savvy Pornhub has not commented. But the bigger question is what Wankz.com may do once it receives the information. It could file a lawsuit against the people who uploaded the videos. It could just send a cease and desist letter. What happens next, however, may be the single most important issue for Pornhub, who relies on users to post content, much of which many in the porn industry say is stolen content. Wankz.com also has refused to comment.
